.net core 日志

Question

在 project.json 添加依赖：

 "dependencies": {
    "Microsoft.Extensions.Logging": "1.1.0",
    "Microsoft.Extensions.Logging.Console": "1.1.0",
    "Microsoft.Extensions.Logging.Debug": "1.1.0"
  },

执行 dotnet restore

测试代码：

using System;
using Microsoft.Extensions.Logging;

namespace Tang
{
    public class Program
    {
        public static void Main(string[] args)
        {
            var loggerFactory = new LoggerFactory()
                .AddConsole()
                .AddDebug();
            var logger = loggerFactory.CreateLogger<Program>();
            logger.LogInformation("This is a test of the emergency broadcast system.");
            logger.LogError("this is error");
            logger.LogWarning("this is warning.");

        }
    }
}
